American Idol's Jena Irene Reveals Why She Voted Against Immunity for All

Which two American Idol contestants chose to have one of their own sent home on Thursday, rather than give everyone immunity?

The vote was anonymous, but PEOPLE can now reveal who voted for immediate elimination – rather than wait a week and have two people sent home then.

“I think I made the right decision. I was prepared for one person to leave,” Jena Irene Asciutto told PEOPLE. “I thought, ‘It is going to be even more nerve-racking next week because we’re going to have two people going home out of five.’ That’s almost half.”

Asciutto says she wasn’t happy to be put in the position of casting a vote that ultimately sent Sam Woolf home. But she also noted that it would have been the second time the heartthrob would have been spared elimination this season.

“It’s always been Sam. Sam went home, and they decided to do a thing,” Asciutto told reporters of Woolf, who was saved by the judges once in April.

None of the other singers owned up to being the second vote for elimination. But with Caleb Johnson, Jessica Meuse and Woolf all saying they voted for immunity, only Alex Preston refused to reveal his vote.

“I don’t really want to say,” Preston told reporters. “I didn’t really care what happened. It was going to be the same outcome no matter what. It was a crappy situation, and it sucks to see Sam go.”
